qdev: Pass size to qbus_create_inplace()

To be passed to object_initialize().

Since commit 39355c3826f5d9a2eb1ce3dc9b4cdd68893769d6 the argument is
void*, so drop some superfluous (BusState *) casts or direct parent
field usages.

virtio-ccw: Wire up guest and host notifies.

Guest and host notifiers are needed by vhost. We use ioeventfds for
the guest notifiers, but need to fall back on qemu injecting interrupts
for the host notifiers.

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....
